USHIO Will Deliver First High-Intensity EUV Light Source Unit to the Netherlands-based Research Institute, TNO

TNO and USHIO are jointly building a new experimental EUV exposure and analysis facility to study radiation induced effects on EUV optics and reticles. The new facility, called EBL2, will support the common goal of understanding of contamination effects on surfaces under all extreme ultraviolet radiation conditions foreseen in the power roadmap for upcoming lithography tools. This will speed up the development of next-generation lithography systems, masks, and pellicles. The USHIO high-intensity Sn LDP (Laser-assisted Discharge-produced Plasma) EUV light source will provide pulsed EUV in a well-controlled environment similar to the lithography system conditions. Sample handling and transport will be automated and have cleanliness levels equal to state-of-the-art semiconductor standards for EUV production.

The USHIO Sn LDP EUV light source can achieve intensity and output of the source approximately 5 to 10 times higher than that of Xenon. Therefore, it enhances the throughput of EUV mask inspection associated with the EUV lithography, which plans to be adopted in the next-generation lithography in and after 2017.

EUV mask technology is critical for the commercialization of EUV lithography and the development of EUV mask inspection tools such as actinic blank inspection (ABI) and actinic pattern inspection (API) and so on is needed. USHIO aims at providing substantial support to the mask inspection process at device manufacturers as well as mask makers by delivering its inspection light sources to mask inspection equipment manufacturers.

USHIO will present the paper relating EUV light source at the “SPIE Advanced Lithography 2016“, to be held on February 21 (Sun.) through 25 (Thu.), 2016, at the San Jose McEnery Convention Center and San Jose Marriot in San Jose, California, USA.
